The problem with philosophical thought experiments

James Wilson has an article up at Aeon, looking at the trolley problem and other ethical and philosophical thought experiments.  One of the things he discusses is the notion that many philosophers have, along with many fans of particular thought experiments, that they're sort of like a scientific experiment.  It's not that unusual for someone … Continue reading The problem with philosophical thought experiments

The spectrum of science to fantasy

Black swans

A question long argued in the philosophy of science is the demarcation problem.  How to we distinguish science from non-science?  Karl Popper famously proposed falsifiability as a criteria.  To be science, a theory must make predictions that could turn out to be wrong.  It must be falsifiable.  Theories that are amorphous or flexible enough to … Continue reading The spectrum of science to fantasy

Maybe we wiped Neanderthals out after all

Or at least, that's the conclusion of a paper which models the population changes and other factors involved. New model to study hominin interactions in time-varying climate environment. Neanderthals experienced rapid population decline due to competitive exclusion. Interbreeding only minor contributor to Neanderthal extinction. Abrupt Climate Change not major cause for demise of Neanderthals. Of … Continue reading Maybe we wiped Neanderthals out after all

The measurement problem, Copenhagen, pilot-wave, and many worlds

With quantum physics, we have a situation where a quantum object, such as a photon, electron, atom or similar scale entity, acts like a wave, spreading out in a superposition, until we look at it (by measuring it in some manner), then it behaves like a particle.  This is known as the measurement problem. Now, … Continue reading The measurement problem, Copenhagen, pilot-wave, and many worlds

Building a consciousness-detector

Joel Frohlich has an interesting article up at Aeon on the possibility of detecting consciousness.  He begins with striking neurological case studies, such as the one of a woman born without a cerebellum, yet fully conscious, indicating that the cerebellum is not necessary for consciousness. He works his way to the sobering cases of consciousness … Continue reading Building a consciousness-detector

The issues with biopsychism

Recently, there was a debate on Twitter between neuroscientists Hakwan Lau and Victor Lamme, both of whose work I've highlighted here before.  Lau is a proponent of higher order theories of consciousness, and Lamme of local recurrent processing theory. The debate began when Lau made a statement about panpsychism, the idea that everything is conscious … Continue reading The issues with biopsychism
